Enabling Objectives

• IDENTIFY PHARS equipment and proper procedures
  IAW Hurst Rescue
• Tool Manual, Phoenix Rescue Tool Manual, and
  Holmatro Rescue Tool Manual.

3
A. Purpose
(1) already proven as a valuable piece of
equipment by civilian fire departments, the
navy has approved the Portable Hydraulic Rescue
System (PHARS) for use as emergency damage
control equipment PHARS can be utilized in
emergency rescue or firefighting operations
involving spreading, lifting, cutting, pulling,
and piercing light plate or sheet metal.

• (2) Currently, there are three different PHARS
  units available in the fleet
• Hurst
• (b) Phoenix
• (c) Holmatro

4
B. Equipment
(1) Power unit

• All tools use a diesel powered engine with a
  hydraulic pump
• Unit pressure for Hurst and Phoenix is 5000 psi.
• Unit pressure for Holmatro is 10,000 psi

(e) Operation of quick disconnect couplings 1)
Align the slot in the sleeve with the pin
9
(e) Operation of quick disconnect couplings
2) slide sleeve back to connect or disconnect the
Coupling
10
(e) Operation of quick disconnect couplings
3) After connecting, rotate sleeve 1/4 to 1/2 of
a turn to prevent inadvertent or accidental
disconnection
11
C. Spreader (jaws of life)

• Hydraulically operated by means of power piston
• (2) Designed for opening, pulling and lifting
• (3) Parts Identification
• (a) Jaws (spreader/aircraft cutter tips)
• (b) Jaw retainer pin
• (c) Connectors(quick disconnect)
• (d) Control valve (trigger)

12
D. Cutting tool

• Hydraulically operated by means of power piston

Designed for cutting sheet metal such as vehicle
roof door posts and vehicle roofs.

• Cutting solid objects over 3/4 in diameter
  should be avoided

• Parts identification
• (a) Cutting blades
• (b) Connectors
• (c) Control valve (trigger)

13
Operation

• (a) When operating, hold blades perpendicular
  to material to be cut
• (b) Material cut must be secured so that it
  cannot twist

14
E. Extension ram

• Hydraulically operated by means of power piston
• Designed for spreading and pulling
• Parts identification
• (a) Feet
• (b) Connectors (quick disconnect)
• (c) Control valve (actuator handle)

15
F. Accessories (1) Multi tool manifold
block (a) Enables more than one piece of
equipment to be connected to power unit
amplifying hose layout. (b) Only one piece
of equipment can be operated at any one time when
using the manifold block (c) Pressure/dump
valve must be in the dump position when adding or
removing equipment from manifold block
16
F. Accessories
(2) Hose reel (a) 100 feet of twinned hose for
remote operation and orderly storage

• (3) Attachment Set
• Increases the capabilities of extension ram
• Includes conical point, base plate,
• v block and wedge

17
G. Operating procedures
(1) Check oil and fuel levels
(2) Before starting unit, check hydraulic fluid
by removing hex bushing (fill cap) on power unit
CAUTION Do not place pressure/dump valve in
pressure position until after fluid level has
been checked and hex bushing replaced
(4) Ensure pressure/dump valve is in the dump
position (5) Place speed lever in the run/start
position (6) Press decompression lever
(7) Hold cage of power unit with one hand and
pull cord with other. Pull cord sharply until
engine starts
WARNING EXHAUST GASES ARE DANGEROUS!!!! Do not
operate power unit in an enclosed area. Exhaust
gases contain carbon monoxide which is odorless
and poisonous and can cause injury or death if
inhaled
(8) Connect desired equipment to power unit (9)
Place pressure/dump valve in pressure position to
operate equipment
WARNING Keep clear of moving parts
(10) When changing equipment , pressure/dump
valve must be placed in the dump position
18
H. Securing procedures

• Place pressure/dump valve in dump position
• Place speed lever in off position
• Close fuel cock
• Storing tools and pump

(a)Compensate for possible build up from thermal
expansion of hydraulic fluid by connecting short
hoses on tool, completing the circuit. Then
moving the trigger in both directions to equalize
the pressure on both sides of the piston
CAUTION Do not close tools completely
(b) Close spreader (jaws of life) within
approximately 1/4 of spreader tips coming in
contact
(c) Close Extension Ram to within
approximately1/4 of tips/ends of cutting blade
meeting
(d) Close Extension Ram to within approximately
1/4 of being completely contracted.
NOTE This will ensure that no undue pressure is
applied to seals within tools
